Review: Noctua NF-A4x10 – The Quiet Upgrade Every Ender 3 Pro Needs - I bought these fans as an upgrade for my Ender 3 Pro, and after installing them (along with the silent motherboard for stepper motor noise), my printer became almost completely silent. The difference is night and day. These fans are super high quality, and I absolutely love how quiet my setup is now. If you're tired of a noisy 3D printer, I can't recommend these fans enough!
Review: I installed this Noctua fan in my Reolink RLN16-410 NVR. It did help to lower the noise from the NVR but not a huge amount. I took 10 sound measurements before and after the Noctua fan upgrade. Min and max recorded values were as follows: With original fan: 45.1 - 46.0 dB With Noctua fan: 43.8 - 45.5 dB These NVRs actually run much quieter with the top case removed, so I also took 10 before and after measurements with the case removed: With original fan, case removed: 41.0 - 42.6 dB With Noctua fan, case removed: 38.5 - 40.0 dB These days I'm running the NVR inside a closed cupboard with the Noctua fan installed and the top case removed and I can only just barely hear the running NVR through the closed (internal wooden) door. I think the lingering noise is actually harddrive noise, not fan noise. Hot tip: I previously also applied weather stripping around the door frame which helped a lot to reduce noise leak through the cupboard door.
